Have had my Ball for 4 years or so and every winter from mid Nov. thru Feb. she goes off feed? Temps are good, 85 cool side which she likes and 90-92 warm side. She lives in a 40 gal. or so tank, and feeds great during Spring and Summer and half of Fall. She eats small live rats. I have been trying to get her to take one with no luck. I guess she is ok, I just get worried she is starving. Does anyone have any pointers to get her to eat?
